The Green Room Collaborative (TGRC) is an international, Scottsdale-based multi-disciplinary landscape architecture practice specializing in highly textural designs aimed at engaging people with the surrounding environment.  The firm was founded by Charlie Ray, ASLA and Brian Kissinger, with collaborating principal Zachary Kiebke, PLA.  From concept to completion, we are focused on designing environments that celebrate a commitment to art, ecology and horticulture, while cultivating a unique sense of place.


Our commitment to horticultural best practices, knowledge of the site, and the exploration of new landscape forms is complemented by an extensive background in all levels of the design and construction processes. We have the interest, knowledge and experience to understand and implement a strategy for project funding and promotion. From the earliest stages of a project, we are committed to provide creative, functional, and highly personalized professional services.


The combined talents and experiences of The Green Room Collaborative places us in a unique and highly qualified niche allowing our team to meet the specific needs of your project.
